Objective To explore the cosmetic effects of the neoplastic incision combined with volume displacement in conserving breast treatment of early breast cancer.

Methods A total of 96 patients, who met the conditions of breast-conserving and had the intention of breast-conserving, were selected, and divided into the plastic breast-conserving group and the conventional breast-conserving group according to their wishes(48 cases each group).According to the location and size of the tumor, the common incisions such as double-ring method, tennis racket, batwing, parallelogram, etc., were individually and flexibly selected in the plastic breast-conserving group.At the same time of tumor resection, the defect of the tumor resection site was filled by volume displacement technology to achieve the purpose of cosmetic breast preservation.Only partial glandular in the conventional breast-conserving group was sutured after the tumor and surrounding glandular tissue resection.The perioperative indexes such as the operation time, intraoperative blood loss, postoperative hospital stay, infection, occurrence of subcutaneous effusion and drainage volume were compared between two groups.The Harris aesthetic score and questionnaire survey were used to evaluate the aesthetic effects, postoperative breast satisfaction, recurrence and metastasis and reoperation of two groups after 6 months of surgery.

Results Compared with the conventional breast-conserving group, the operation time was longer, the intraoperative blood loss was more (P < 0.01), and the total drainage volume after 3 days of surgery decreased in the plastic breast-conserving group(P < 0.01).There was no statistical significance in the hospital stay between two groups(P > 0.05).There was no statistical significance in the subcutaneous effusion, incision infection, flap necrosis and disruption of incision between two groups(P > 0.05).After 6 months of follow-up, the cosmetic effects and patient satisfaction in the plastic breast-conserving group were significantly higher than those in conventional breast-conserving group(P < 0.01), and there was no statistical significance in the rates of local recurrence, metastasis and reoperation between two groups(P > 0.05).

Conclusions The neoplastic incision combined with volume displacement combines tumor resection and plastic surgery techniques, takes into account aesthetic effects, does not increase the risk of surgical complications and tumor recurrence and metastasis, provides patients with a more humane treatment choice, and improves patients' postoperative quality of life.
